Ourinvention relates to adjustable mountings for motors and other small units of machinery.

It is an object of our invention to provide a base for a motor which maybe readily adjusted so as to shift the motor.

' A further object is to provide an adjustable sliding base for motors which is simple in construction, is very rigid and which can '10 be quickly and easily adjusted so as to clamp the motor base in any desired position. i

* Other objects will appear from the following description,

accompanying. drawings, in which ,I I

Figure 1 is a plan view of the sliding base 7 I with the motor shown in position in dotted lines;

,Figure- 2 is an end elevation thereof; and

. Figure 3 is a side elevation thereof, parts 0 being shown broken away at the vertical plane through the center line of the bolt.

' The base plate 4 to which the motor- 7 may be bolted has depending flanges 4' formed at its ends, and rests on two parallel angle irons 5 which form the guides for the base late and which are suitably secured to the oundation' support 6. Each of the flanges 4* has an L-shaped slot 4 formed therein near drilled in the vertical portions of the angle irons 5 and, also through the slots 4" in the depending flanges 4. tions of the slots 4* ment of the position of the motor or dynamo 7 to properly tension its belt, while the vertical portions permit the ready removal of base plate and motor by raising them from the angle irons, without removing the bolt. The bolt is threaded at its ends to receive the nuts 9 and 10, and a locking plate 12 which is screwed on at the ri lit-hand end (Fig. 3 of the bolt 8. Throug the engagement 0 its pendant portion 12' with the foundation suport 6., the lockin plate prevents rotation of thebolt. The bo t passes through a tubular separator or spacing member 11 which fits snugly between the v'ert1cal portions of the angle irons 5. v

reference being had to the' the central portion of the flange. I 30 A bolt 8 extends through the suitable holes The horizontal por-' permit the base to be slid 'on the angle irons 5 to provide for ad ust-- The plate 4 may be readily removed from and replaced on the angle irons 5 by sliding it to the right (Fig. 2) and raising it permitting the bolt to pass through the vertical end of the L-shaped slot 4". Upon tightening the nut 10 there will be a frictional clamping action between each ofthe depending flan es 4 and its adjacent angle iron 5 due tothe mterposition of the separator 11,;and thus bythe one nut,

merely loosening and tightenin clamped in the motor may be shifted an any desired position. I

It will be apparent to those skilled in the art that slight changes, such as cutting the slots in the angle irons instead of in the base flanges, may be made without departure from 4 the-principles of our invention. We do not wish to limit our invent1on to the exact struc-v I ture disclosed, but whatwe claim and desire to secure by Letters Patent is:

1. In an adjustable mountingfor motors, the combination of a plate having downwardly extending flanges at its opposite sides, each of said flanges having a centrally located open end L- haped slot, a pair of supporting angles positioned adjacent said flanges, a bolt extendin through said angles and the slots in said anges, a spacing or nvansvrnmmnmna, ,assrenons, or new You, 11. Y., A conroaarrox member surrounding said'bolt and fitting between the I I inner surfaces of saidangles, and means to prevent rotation of one end of said bolt so that said flanges may be frictionally clamped totheir adjacent angle plates by drawing up 'the nut at the other end of said bolt.

2. An adjustable mounting for machinery, comprising a pair of upwardly extending supporting members, a plate restmg luplon the upper ed es of said members and avin downwar ly extending flanges adjacent sai members, said flanges having similar longitudinal slots therein, a bolt passing through said membersand having its ends project ng through said slots, a separator between said of said bolt so that both of said flanges may be 'frictionally members by tightening the nut at one end of said bolt. I

3. An adjustableimotor'base, com rising a base plate to which a motor is a apted to members, and means for preventing rotation o5- clamped to their adjacent 1 vent rotation thereof so that be secured, said plate having depending flanges at its sides, said flanges having opposed L-shaped slots therein, a pair of guiding and supporting angle irons having vertical surfaces in contact with saidflan es, a. bolt extendin through said .angles an said slots in said anges, a member surrounding said bolt for maintaining said angle irons in-spaced relation, and alockingplate secured at one end of tation thereof.

'4.'In an adjustable mounting for machinery, a base plate, supporting means therefor,

said base plate and said supporting means having pairs of respectively juxtaposed flanges, a bolt passing through said flanges, said bolt being held against lateral movement in one pair and laterally slidable in slots in the other pair of said flanges, a spacing member surrounding said bolt and adapted to separate a pair of said flanges, a locking plate secured to one end; of said bolt to preupon tightening the nut at the other end of said bolt said pairs of flanges may be frictionally clamped together to secure said base plate to .said support. I a

5. An adjustable mounting for machinery comprising a movable base plate individually adapted to support a motor or the like having longitudinally extending lateral bearing surfaces at its outer lateralssides, parallel supporting members having longitudinally extending bearing surfaces adapted to coact with the aforesaid lateral surfaces and a single transversely extending'member passing through the base plate and said members adapted to simultaneous y clamp said surfaces together.

6. An adjustable mounting for machinery comprising a movable base plate individually adapted to support a motor or the like having longitudinally extending side flanges having lateral bearing surfaces, parallel supporting members hav ng longitudinally extending bearing surfaces adapted to. coact with the aforesaid lateral surfaces, a single trans versely extending bolting member adapted to simultaneously clamp said surfaces together and a tubular separator surrounding said bolting'member and serving to maintain said parallel supporting members in alignment.

In witness whereof, we hereunto subscribe our names this 12th day of April 1926.
